International Conference on Additive Manufacturing

Before additively manufactured parts can be used in safety-critical applications, a clear understanding of the entire process chain and feedstock-process-structure-property-performance relationships must be established. ICAM 2022 will be the largest ASTM International scientific conference and intended to provide a forum for the exchange of ideas and to transition the research to applications, focusing on the need for industry-specific standards and design principles as well as challenges with qualification and certification.

The first event, a May 2016 workshop, was sponsored by the committee on fatigue and fracture (E08) in San Antonio, Texas. The second event, a November 2017 symposium, was sponsored by E08 committee and the committee on additive manufacturing technologies (F42) in Atlanta, Georgia. The third event in November 2018, sponsored by the F42, E08, and E07 (nondestructive testing) committees, was held in the Washington, D.C. After the creation of ASTM International Additive Manufacturing Center of Excellence (AM CoE) in 2018 and the growth of the additive manufacturing industry, the 4th event, held in Washington, D.C. area in 2019, was led by the AM CoE and dozens of involved additional technical committees. In 2020, the ASTM AM CoE decided to offer this gathering as a major conference. The ASTM International Conference on Additive Manufacturing (ICAM 2020) included 19 symposia and 10 panels, held over 5 days with 5 parallel sessions. Due to the pandemic, the ICAM 2020 was organized virtually with over 300 presentations and close to 600 participants. ICAM 2021 grew to a hybrid event held in Anaheim, CA and online, in November 2021 with over 850 participants, including 26 symposia, 11 panel discussions, and 7 keynote addresses.

This year’s event, the ASTM International Conference on Additive Manufacturing (ASTM ICAM 2022), will have a broader scope related to standardization, qualification, and certification of AM products. This event will involve even more ASTM committees and external stakeholders, setting the stage to bring experts from around the world to exchange the latest developments in the field of additive and advanced manufacturing towards the 4th industrial revolution. We invite the entire community to join us for the exchange of ideas, to learn about the most recent advancements in the field, and to be a part of the journey for transitioning research to application through standardization.

Polymers form a significant portion of additively manufactured printed products. Challenges with implementing polymer based additive manufacturing include material and process standardization, unique test standards, lack of documented design, analysis, qualification and certification methods, and a limited trained workforce.

Additive manufacturing feedstocks are available for a broad range of material types and in various forms, including powder, wire, filament, inks, etc. New offerings are continuously introduced to the market with varied and unique characteristics. In some cases, all of the critical feedstock characteristics which significantly impact the quality of each process step are not fully understood quantitatively. Therefore, a proper understanding of AM feedstock characteristics and key variables contributing to their performance can be essential for production of AM parts with repeatable quality. New characterization methods, acceptance criteria, and standards are to be developed for the complete characterization of the feedstock materials.

Additive manufacturing enables modernization and more capable defense systems through the fabrication of highly optimized and complex parts. It also enables improved readiness by providing an alternative route to manufacturing hard to source spare parts and parts at the point of need, e.g. by battle damage repair or temporary spare parts manufactured onsite. Because of this, the defense industry has taken a lead in advancing and maturing this technology. However, the existing commercial standards, military standards, airworthiness standards, and certification practices may be difficult to apply or are not relevant to AM parts. Thus, new standards and practices need to be developed to facilitate broader and more rapid adoption.

Additive manufacturing has evolved over the past decade and research has primarily focused on the evaluation of microstructure characterization and mechanical performance with limited emphasis on environmentally induced degradation modes. However, understanding environmental effects (e.g., corrosion, decomposition, stress corrosion cracking, etc.) on additively manufactured alloys is critical to enable use in structural components for engineering applications.

The rapid adoption of additive manufacturing across numerous industry sectors with a wide variety of applications requires methodologies for the characterization and mitigation of risk arising from material flaws. For safety-critical applications, it is particularly important to understand how material characteristics and process defects typical to AM (e.g., pores, lack of fusion, surface roughness, etc.) affect component integrity. Understanding these effects is complicated by the lack of historical data, the potential for variability in AM processes, and the rapid evolution of the technology. The qualification, certification, and safe continued use of AM products in fatigue-critical applications will depend not only on a basic understanding of damage mechanisms and the associated behavior of typical AM defects, but also on the development of robust, validated models and software for predicting fatigue life and fracture risk.

The rapid advancement of additive manufacturing technologies and increased adoption of the technologies in industry have coincided with the emergence of artificial intelligence and machine learning (AI & ML) in the mainstream. A massive amount of data is being generated in AM from various steps of the AM process, including design, process planning, building, in-situ monitoring, post-processing, inspection, characterization, and testing, as well as operation performance, during the service life of the component. Further, a high number of parameters are being defined for monitoring and control of AM processes. Both data and parameters make AM a great candidate for AI and ML applications. The objective of applying AI & ML is to better understand underlying physical phenomena in AM and fine tune the AM processes.

Advancing towards the vision of Industry 4.0, information sharing via a distributed manufacturing framework internally in an organization and over the global internet becomes increasingly utilized with additive manufacturing. AM is a direct digital manufacturing method, and as the AM equipment becomes more closely interconnected with other components of Industry 4.0, it becomes exposed to a variety of cyber- and cyber-physical attacks. Therefore, security of AM should be addressed in a holistic manner. This includes but is not limited to identifying cyber-security threats in AM and how they can be addressed, to ensure and support the advancing of manufacturing to a whole new level. This symposium explores specific security aspects for AM in an Industry 4.0 environment.

Additive manufacturing presents us with a unique opportunity of generating massive amounts of data from various steps of the AM process, including design, process planning, building, in-situ monitoring, post-processing, inspection, characterization, and testing, as well as operation performance, during the service life of the component. While such data can be used to better understand key process variables (KPVs) and support decision making, it simultaneously presents a big data management challenge. Methods of AM data labeling, acquisition, storage, analysis, security, and sharing are yet to be fully explored. While many companies have developed internal procedures to address the above challenges, the AM community would benefit from standards and best practices that are widely accepted and available to the general public, particularly small and medium size enterprises (SMEs).

Established testing standards exist for deriving different mechanical properties; however, it has become clear that conventional procedures may not always be applicable to additive manufactured materials due to the nature of the additive fabrication process. Additionally, unique mechanical characteristics and property dependence often exist under different conditions such as geometry, process parameters and post-process procedures.

Key performance metrics and characteristic properties of additively manufactured components are often different from their conventionally manufactured counterparts, owing to AM materials’ distinctive microstructural features (e.g., strong texture, columnar grains, etc.) and possible process induced defects (e.g. lack of fusion/pores, cracks, surface features, etc.). These characteristics arise because of processing conditions unique to AM, such as layer-wise fabrication and exceptionally high cooling rates. It is therefore important to explore the various microstructural characteristics of AM materials and their impact on properties via experiments, models and simulations.

While destructive evaluation methods such as mechanical testing and microstructural characterizations are often used to evaluate mechanical performance of additive manufacturing materials and parts, nondestructive evaluation (NDE) methods can provide significant insights without the need for sectioning and damaging the part. Due to the fact that the mechanical performance of AM parts is often significantly influenced by the presence of defects (i.e., pores, lack of fusion, surface roughness, etc.), understanding the critical characteristics, such as type, size, distribution, and location is key to managing performance expectations and qualification.

The interest in sinter-based additive manufacturing processes continues to rapidly grow with the promise of enabling new applications by significantly reducing production costs. Sinter-based AM processes now include Binder Jetting (BJT), Material Extrusion (MEX), Material Jetting (MJT) and Vat Photopolymerization (VPP) technologies. Unique In these processes, powder material is bound together with a binding agent during the printing process, commonly referred to as a “green” or “brown” part. Secondary debinding and sintering steps are required to remove the binding agent and consolidate the powder material to the desired final density. While the potential is high, there are many challenges involved in these processes.
